The average reading speed of students completing a speed-reading course is 435 words per minute (wpm). If the standard deviation

nekit [7.7K]

Answer:

$Z = -1.58$

Z = -1.58 means that a reading speed of 340 wpm is 1.58 standard deviations below the mean reading speed.

$Z = 0.67$

Z = 0.67 means that a reading speed of 475 wpm is 0.67 standard deviations above the mean reading speed.

$Z = -0.25$

Z = -0.25 means that a reading speed of 420 wpm is 0.25 standard deviations below the mean reading speed.

$Z = 2.92$

Z = 2.92 means that a reading speed of 610 wpm is 2.92 standard deviations above the mean reading speed.

Step-by-step explanation:

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations a measure X is above or below the mean.

In this problem, we have that:

$\mu = 435, \sigma = 60$

a. 340 wpm

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{340 - 435}{60}$

$Z = -1.58$

Z = -1.58 means that a reading speed of 340 wpm is 1.58 standard deviations below the mean reading speed.

b. 475 wpm

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{475 - 435}{60}$

$Z = 0.67$

Z = 0.67 means that a reading speed of 475 wpm is 0.67 standard deviations above the mean reading speed.

c. 420wpm

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{420 - 435}{60}$

$Z = -0.25$

Z = -0.25 means that a reading speed of 420 wpm is 0.25 standard deviations below the mean reading speed.

d. 610wpm

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{610 - 435}{60}$

$Z = 2.92$

Z = 2.92 means that a reading speed of 610 wpm is 2.92 standard deviations above the mean reading speed.

I need help with this

ddd [48]

Answer:

n = √3

m = √3

Step-by-step explanation:

The triangle is an isosceles right triangle with 2 equal base angles of 45° each.

Thus:

Reference angle = 45°

Hypotenuse = √6

Opposite = m

Adjacent = n

✔️To find m, apply the trigonometric function SOH, we have:

Sin 45 = opp/hyp

Sin 45 = m/√6

√6 × 1/√2 = m (sin 45 = 1/√2)

√6/√2 = m

√(6/2) = m

√3 = m

m = √3

✔️To find n, apply the trigonometric function, CAH:

Cos 45 = adj/hyp

Cos 45 = n/√6

√6 × √2/2 = n (cos 45 = √2/2)

√12/2 = n

√(4*3)/2 = n

(2√3)/2 = n

√3 = n

n = √3
